Why teams connect Customer.io and Veeva CRM

Sync what happens in Customer.io with the customer records in Veeva CRM, in real time and in both directions.

The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Customer.io holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.

Stacksync connects Newsletters, People, Objects, Events in Customer.io to Calls, Medical Inquiries, Sample Transactions, Consent Records in Veeva CRM with bi-directional, real-time sync. Activity and record changes in Customer.io update the matching contact or account in Veeva CRM, and CRM data flows the other way wherever Customer.io can store and use it.

Common use cases

  • Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • Feed territory alignments from a roster system into Veeva as field teams change.
  • Mirror medical inquiries into a medical information system for fulfillment and audit.
